My USB Audio Recorder has an ON/OFF switch which broke and needs to be replaced. The replacement should ideally be the same type of switch. From the photos, do you know what this switch is or which component could replace it?

I do not know the vendor of the USB recorder. It seems like a generic white label device that's sold by different re-sellers. A user manual is available from multiple brands, for example:

I have not found a vendor, hence I do not know the type of the switch they've used.

The switch has only 2 positions: ON vs OFF. When it's ON, the device will be on and recording. When it's off, the device stops recording and records can be accessed via USB. Now, when the switch is broken it's mechanically damaged and the device is always in the recording mode.

The product, whose vendor is unknown to me, is for example on amazon:

Doing some cleanup around the house. Realized I have 3-4 PC's sitting around only used for clients who refuse to update older machines. I keep the older software on them for those special situations. I also have large hard drives on them. I thought it might be a good idea to do one of a few things. Your wisdom appreciated other than the obvious throw them away!
  • Salvage any and all components HD's Wireless Adapters Graphics Cards USB etc.  I am guessing that some of the HD should work universally right?
  • Move some of them over to a new modern Motherboard 64 bit with more horsepower RAM performance. ( I realize that the problems I may run into are compatibility, non-supported drivers OS issues and probably BIOS stuff. )
  • I was thinking by consolidating some of the data I might be able to get some more use like backup space etc.
  • Take the hard drives and create some kind of file server and or printer server with a machine or two.

Out of Curiosity, I was wondering since several of these have older OS's on them would it be of any value to keep a few older OS with software that works with it Crystal Reports Business Object Enterprise. Tableau Desktop on some of them. Is it possible to put them on a box that at StartUp allows me to pick and choose what OS I startup with?

We have jumped from a 17 inch monitor to a 22 inch. The 22 model is black in color and 1/2 inch thick and the setting buttons are on the bottom of the screen and not clearly marked. We went to the control panel and there are about 20 resolution settings. We played around with some of those and on those far higher than 800 x 600 got us "input not supported."

What would be the best place to start for step 1 in getting the settings the way we desire: Control panel settings for displays "or" the settings offered on the monitor.
The width is fine but the height is leaving off too much.
I have Power Supply and Motherboard from HP Z420 workstation. I bought a case for it: Corsair 275R. The problem is that HP's PSU will not fit there at all and even if it did, the CPU cable would not reach the top of the motherboard where it is supposed to be plugged. So I have a new PSU: Corsair VS550. The problem is that ATX and CPU plugs are different on HP's power supply and Corsair's one. See attached pictures. Does it mean that HP is custom that I won't be able to get PSU for that motherboard or I can't use that specific Corsair I have and have to get something else? or am I missing something else?

Thx in advance
We are having issues with our PKI infrastructure. We have an offline root ca and an enterprise subordinate CA running on windows 2012 r2.
I want to verify the health of the pki.
1.      Is the root CA certificate valid
2.      Is the root CRL still valid
3.      Is the subordinate CA certificate valid,
4.      Is the subordinate CA CRL still valid.
Certificates issued earlier and were working fine are now showing errors like “revocation check failed”.
How do I verify the PKI components are healthy and are valid.
SITECORE: Key differences between Core, Master and Web

I am new to Sitecore and seek a simple explanation of the key differences between Core, Master and Web.

Also, is Sitecore considered a form of "cloud computing"?

my computer is only using 3gb of RAM,  but there is 6gb installed. it says only 3gb is usable. why might this be and how can i fix it?

I am trying to use a ASUS M5A78L-M Plus/USB3 motherboard along with Wirecast and was told that my built-in graphics card, the Radeon 3000, will only support DirectX 10.  I need at least DirectX 11 to run Wirecast, so I just want to make sure that I understand this correctly.  

It seems the only expansion slots on this machine are:
1 x PCIe 2.0 x16
1 x PCIe 2.0 x1
1 x PCI

Is there even an external PCI graphics card that can run DirectX 11 or do I just build another computer?
Does the Western Digital Ultrastar 14TB DC HC530 7200 RPM SATA 6.0Gb/s 3.5" Data Center Internal Hard Drive - 0F31284 come with a 5-year warranty or a 2 year warranty? On the website it says Up to 2.5M hours MTBF with a 5-year limited warranty but under the warranty and returns Limited Warranty period parts and labor 2 years.

To extend my thinkpad's battery life longer, I wud like to set it such that only when

a) it's below 80%, it will charge till 100% when the power plug is connected & 
b) it will not charge the battery at above 80% & the laptop will
     run purely on AC power when plugged in
c) ideally (may not be feasible) that while charging the battery from 79% to 100%,
     it runs purely on AC

I'm developing a Bootstrap project and started out with a UI kit theme but found that tweaking it was an issue, so I'm now using standard-issue Bootstrap.  My question is what or where are recommended/best form UI Components?  I've researched, but am not sure which are quality ones, so recommendations or a guide to resources is appreciated.   I usually use Foundation, and this project is also new to me as it is financial and has dates, amounts, percentages and charts.

hi guys

I'm trying to buy registered (buffered) RAM. When I search for it for example on Amazon, it doesn't say registered or buffered. I can see that ram that is unbuffered is clearly labelled. Am I right in assuming that when it does not say unbuffered, that it is registered?

thanks for helping
We have windows Server 2016 we run SFC /scannow and its unable to repair components.  I also Try DISM restore health and RPC Service is not available.  Even though RPC is set to automatic and running.  I then try DISM with Source file and I get source file not found.  Looking for any help appreciated.
This is a real doozie! Dell T7500 workstation. Began with both front fans ramping up slowly from normal slow speed to full on. The computer seemed to operate normally. POST said the fan was defective. I replaced every fan in the unit except or the one in the power supply. No change. I replaced the video card with an unused Nvidia Quadra 4000. No change. I unplugged the hard drive. No change. At this point I am a bit desperate. I spoke to a technician that said the motherboard was the trouble. I then replaced the MB with a tested used one. Again...same problem. The ONLY components left is the power supply and the ram memory. So, I had an unused DEll identical part number PS available. After install? You guessed it. Same problem. Then the last thing I tried was a tested cpu that had identical numbers and specs. Again, a waste of time and money. ONLY the ram is left. I tested it using the long test and it shows as OK. Where do I turn at this point?
I want to connect my LCD TV to a laptop about 25-30ft away.  Stream movies.  Now its sitting right next to that TV and connected VGA and sound cables separately.
 TV has HDMI ports and laptop has a DisplayPort.  If I find HDMI to DisplayPort cable.  Would it carry a sound also?

Any other ways to connect wireless may?

Does any Expert know of an organization that supplies surplus / used computers to the elderly? I know of a person on a fixed low income that cannot come close to afford to purchase a computer. She lives in Oklahoma and is in a small town and is somewhat isolated. A computer would make a great difference in this person's life. I had seen many years ago a story detailing a young man in his teens that collected anything and everything and reassembled components for this exact purpose. If anyone knows of such a program please let me know so that I can turn this person's information over to them for consideration. This person is an education magnet! She reads every book she can get her hands on and would feel like she were in heaven if she had the ability to be on the internet. At the moment she has been loaned a small 8 inch palm type device but due to the size and the slow speed it is virtually useless. I personally would pay it forward to her some sort of book club subscription if she was able to obtain the computer. It IS the season for love and giving. Any thoughts or ideas would be appreciated.

Using  serversocket and clientsocket components I could build a chat program with delphi xe 10 seattled.
When ClientSocket is connected to a localHost with host='' and  port=21 and the ServerSocket activated with Port=21 then every thing is going well and the communication was established.
However I would like to transfer my ServerApplication(with ServerSocket) to a real server(not a local one). I have two options:
1. Simply using my web (hosted in a server which is not mine)
2. Purchase a server for my own.
In both cases I don't know how to do it...
Please help!

Does a PCI Express graphics card's power draw depend on the type of slot it is put in?

Example Scenario:  A PCIe graphics card that is designed for a PCI Express 3 slot is placed in a PCI Express 2 or 1 slot.  It is thus unable to produce the maximum output it has been designed for, if it was in a PCI Express 3 slot.  In this situation does it require less power to produce it's output seeing as it is restricted in where it is?

Added to question:  Power coming from PCI Express slot only.
